WIPER FOR SPINN I1\T Gr-MAOHINES.

Specification of Letters Patent.

Patented Feb. 12, 1918.

Application filed July 13, 1917. Serial No. 180,424.

To all whom it may concern:

Be it known that I, GUS F. ROBERTS, a citizen of the United States, residing at Belton, in the county of Anderson and State of South Carolina, have invented certain new and useful Improvements in Wipers for Spinning-Machines, of which the following is a specification. V

This invention relates to certain new and useful improvements in cleaning devices for spinning machines and the like, and contemplates more especially an improvement over that form of combined wiper and cleaning cord disclosed in United States Letters Patent No. 1,129,312, granted to me February 23, 1915.

The invention aims to provide improved means for removing the accumulation of lint from the frames of spinning machines and particularly the thread-boards, roller beams, back boards, and creels thereof.

The attaching the wipers to the cord, and a further object is to sufliciently reinforce and stiffen the wipers for maintaining a full and uniform sweep of the space to be cleaned.

In the accompanying drawings:

Figure 1 is a perspective view of a portion of the endless cleaning cord having attached thereto a wiping member which is stifiened or reinforced a distance on each side of the V cord, as shown.

Fig. 2 is a longitudinal sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary perspective view of a spinning machine, illustrating the manner in which the plurality of endless cleaning cords and wipers are tensioned and driven on the thread-boards and creels.

The improved cleaning device, and more especially the endless cord and attached wipmg members, have been designed to overcome certain difficulties which have been exf perienced in using that form of cleaning cord disclosed in my patent hereinbefore referred to. It has been found from prac- 3 tice that the endless cord continuing to move Ll in one direction sometimes causes the wipers, g which are made of flannel or other suitable material, to droop rearwardly and ulti-' mately lie substantially close to or hug the cord, thereby reducing the width of the path primary object is improved means for commercial value, in that and the wiper can be occasioning necessarily the stopping of the machine and the introducing of, another set of cleaning wipers at an increased expense.

I avoid this Waste by reinforcing the projecting wipers so as to maintain a substan tially uniform path of travel and thereby clean a corresponding predetermined surface of the machine- The reinforcing of the wiping members I accomplish by stiffening the laterally extending ends of the wipers for a distance on each side of the cord. In the form herein shown, the wiper is doubled back on itself at its intermediate portion thereby forming an increased thickness of the material. The stiffening of the wiper may also be accomplished by otherwise increasing the ply of the material at its central portion.

The positioning of the wiper upon the cord or rope also produces added advantages of the wiper is pre f erably interposed between the strands of the rope, as shown. In the use of a twostrand rope the strands may be untwisted readily inserted therebetween and stitched at one end to guard against any tendency to work loose. The manner of attaching the wiping members to the cord can be varied and I do not care to lfiimipl myself to the exact manner herein set ort Referring to the drawing, the general type of spinning machine to which my invention is applied comprises the usual frame 1 on which are supported the thread-boards 2, roller beams 3, back boards l, and double creel 5. The drawing rolls are indicated at 6 and the roving bobbins are shown at 7. This form of spinning machine is well known in the art and a further detail description thereof is not deemed necessary.

The cleaning devices are positioned upon the machine in groups and are adapted to clearthe respective surfaces over which they pass of all lint and other foreign substances.

Inasmuch as these several cleaning devices I are similar in construction and operation a description of but one group only will be given. The endless cords or ropes 8 are designed to traverse a surface of the spinning machine including the thread-boards,

:,: stit ching. 23 along theysingle ply and treble ply portions to prevent raveling. Thus there-.are -provided the multiply portion engaging the. cord looped end of the cord and .12. By this construction the ness of the cord is always maintained. Each .beneaththe bed of "pullevs Mare provided on the shaft 13, and

which is rotated roller beams, manner that the group of cleaning devices is provided with the-guiding pulleys and weighted tensioning device.

The endless cordsare driven from a common drive shaft 18- transversely positioned the machlne.

interrupt the horizontal path of travel of the cords which are adapted to pass around said drive pulleys and receive motion therefrom.

' Poweris transmittedto the drive shaft 13 through bevel gears 15. and 16, the latter of by the shaft 17 suitably driven from any source of power connected to the machine, as will be readily understood.

The cords or ropes are preferably formed ,of twisted strands and for the purposes here- ;in shown I employ av two-strand rope twisted' in the usual. manner. The wiping members 18 are readily attached tothe cord- 8 preferably between the strands thereof. The materialfrom which the wipers 18 are made maybe of flannel-or other suitable material, which readily collects lintand at the same time maintains uniform projectingstabilityiwithres ect tothe surfaceover which it.-sweeps. The form of wiper shown 1 in .;Fig. -1 of the drawingsincludes a-strip of fabric 19 bent back or doubled uponitself,

as at 20,;and extended beneath the main portion 19 to, the po nt20 vand there bent upon atself aga n and continued toform the projectingportion 2,1. The double backed port ons are stitchedwas at 22. .I also provide andv extending an effective distance.lIlfubOtllIllI'QCtlOIlS from the cord,

The relative strength of the. twisted strands of the cord is usually sufiicient to hold the. fabriciwiperin place, but in addition to this I provide stitching '24 at the front or leading edge of the wiper, as shown. From this construction of wiping member it will be apparent that I haveproduced a relatively stable and yet sufiiciently flexible cleaning wiper for the purposes to which it is subjected. V l
